大般涅槃經疏 18.28

18.28

From "Good son, when my Dharma is extinguished" onwards is the fourth [part], which again concludes with the Dharma of Śākyamuni Buddha. This also has three [parts]: first, explaining that as it is about to be extinguished, disputes will arise; second, explaining that in the country of Kauśāmbī the Buddha's Dharma will thereupon be extinguished; third, the great assembly laments in sorrow. The first text is as explained in the "Kāśyapa Chapter". As for 'lac' (lakṣā), Hexi says: it comes from the palāśa tree; when it emerges it is purely worms, and foreign countries use it to dye wool. From "At that time, in Kauśāmbī" onwards is the second [part], explaining that the Buddha's Dharma will thereupon be extinguished, being brought to extinction because six hundred [bhikṣus] initiate disputes and harm one another. From "At that time, in Kuśinagara" onwards is the third [part], the great assembly lamenting in sorrow. This also has three [parts]: first, the great assembly laments in sorrow; next, Kāśyapa consoles them; third, the sorrow of the great assembly ceases and they generate the mind [aspiring to awakening]. That is to say, hearing of its extinction they grieve, and hearing of its non-extinction their grief ceases. Realizing that it is neither extinguished nor unextinguished, they then generate the mind. Therefore, know that being neither extinguished nor unextinguished, yet extinguished and not extinguished, it brings great benefit.
